SPECIFICATION. TO ALL WHOM IT MAY CONOERN:

Be it known that I, GEORGE H. REYNOLDS, of Peoria, in the county of Peoria, and State of Illinois, have invented a new and useful improvement in Bran Duster; and I do hereby declare that the following is a full, clear, and eXact description thereof, which will enable others skilled in the art to Ymake and'use the same, reference being had to the accompanying drawings, forming part of this speciiicatioin-in which- I i Figure 1 isla top view of my improved bran duster, partly in section through the line ze, figure 2.

Figure 2 is a vertical longitudinal section of the same taken through the line :c w, ligure l.

Figure 3 is a detail side View of the upper part of the apparatus.

Figure 4 is a horizontal cross section ofthe same taken through the line yy, ligure 2.

Similar letters of reference indicate like parts. i

My invention has for its object to.4 furnish an improved apparatus by means of which the flour adhering to the bran may be readily and thoroughly separated therefrom, and it consists, first, in the combination of the convex and concave cones, constructedas hereinafter described, with each other, with the driving shaft, and with the frame of the apparatus; second, in the combination of the stationary and movable spiked heads with each other, with the driving shaft, and with the frame of the apparatus; third, in the combination and arrangement of weights, levers, uprights, and cams, and gear wheels, with each other, Withthe driving shaft, with the frame of the machine, and with the frames to which the wire bolt cloth is attached.

A is the frame of the machine, B is the central or driving shaft; this shaft is vertical and it is supported, and its lower end revolves in a step,C, as shown in figure 2. This'step is cup-shaped to contain the lubricating oil, and it is covered with a cup, c1, to keep out theldust and dirt. The upper end of the shaft, B, revolvcs'in bearings D, attached to the frame,` A, of the machine; E is a convex cone attached to the upper part of the shaft B. This cone may be made double, as shown in the drawings, or it may be made single, as maybe desired. Upon the convex surface of the cone E, are formed ribs, e", which are notched or toothed as shown in figures 1 and 2. F is a concave cone surrounding the cone E, as shown in the drawings. The inner or concave surface of this cone isribbed to correspond with the ribs Vformed upon the convex surface of the cone E. These ribs, f', are also toothed or notched in such a way that the projections of the ribs f may enter and Work in the notches in the ribs, e, as shown in iigure 2, when the shaft B and cone E are revolved. To the lower side of the platform G, that supports the cone F, is attached an immovable head, H, the lower surface of which is filled with downwardly projecting spikes, as shown` in gure 2. The middle part of the head H, is cut away as shown, so that the b-ran may pass freely from the space between the convex and concave cones to the space between the immovable head H and the movable head I. The movable head I is attached to the shaft B, and has its upper surface filled with spikes so arranged as to pass between the spikes of the head H, as shown in figure 2. The head I is of such a size as to leave a space all around its edge, through which the bran may pass into thc bolt beneath. To the lower surface of the movable head I is attached the upper ends of the wings J, the lower parts of which are attached to arms, K, extending out from the shaft B, as shown in figures 2 and 4. The forward or outer edges of the wings, J, are notched as shown and they are set inclined; the lower end of each wing being in advance of the upper end, sothat the tendency of the wings may be constantly to uplift the bran.` L is a spout through which the bran finally escapes from the duster. M is the wire bolt cloth which is attached to a framework, consisting of vertical ribs, N, and circular end pieces, O. `The spaces between the vertical ribs lead through holes in the bottom, P, of the bolt, into the chamber R, formed between the bottom, P, ofthe bolt and the bottom, S, of the duster. T is the outer casing that encloses the bolt. U are arms attached to the shaft, and which, as the shaft revolves, sweep around the chamber, It, moving the flour into such a position that it can escape through the spout V. To the upper end of the shaft B is attached a pinion wheel, W, the pinions of which mesh into the teeth of the wheel X, which revolves upon a spindle, A), attached to the frame, A, of the duster. Upon the lower side of the wheel X are formed two` or more cams, B', as shown in figure 2, which as the said wheel revolves come in contact with the upper ends of the uprights C', and depress them. The lower ends ofthe uprights C rest upon and are pivoted to the ends of the levers D', as shown in figure 3. To the other ends kof the levers D are pivoted the ends of the levers E', the other ends of which are pivoted to the frame, A, of the duster, as shown in figure 1. F are weights attached tolthe levers D and E', which rest upon lvthe heads ofthe pins G. These pins pass through the platform Gr, and their lower ends rest upon the upper end pieces, O, of the frame to which the bolt cloth M is attached, as shown in figure As the upright C .are depressed by the earns B', they operate the levers D'and E', and raise the weights Ffgwhich, when the 'uprghts are freed from the cams, fall upon he pins G and jar the bolt cloth so as to keep the meshes open for the passa-ge of the Hour. The bran may be introduced Vinto the hopper, H', from a. shaker by means of which cobs, nails, dough-balls, &c., which may be in the bran, are separated from it before it enters the duster. The bran upon entering the duster passes down between the convexy and concave cones, inte the space between the immovable and movable heads H and I, thence it passe-s down around the edge of the movable head I into the bolt, and then out through the spout L'. The flour disengaged from the bren during its passage through the (luster, passes through the bolt cloth M, and thence downinto the chamber R, from which it passes out through the spout V.

What I claim ss new, and desire to secure by Letters Paltent, is-

Tlie bran duster consisting of the ribbed one E, ribbed eneesing cone F, spiked stationary head H,spiked movnblehead I, winged' arms K, bolt-frame M, chamber R, arms U, enclosing case T, uprights C", Weighted levers D', and levers E', arranged und operating substantially as described for the' purpose specified.
